I'm trying to understand the field "CPU Pinning topology" in the "Ressource
Allocation" tab, that looks it needed by High Performance VM.
I have this hardware:
# lscpu
Architecture: x86_64
CPU(s): 48
On-line CPU(s) list: 0-47
Thread(s) per core: 2
Core(s) per socket: 12
Socket(s): 2
NUMA node(s): 2
And I want to run a 22 vCPU vm on it, so no SMT, and 11 vCPU mapped to each
socket.
The only explanation I found about this field content was here:
https://rhv.bradmin.org/ovirt-engine/docs/Virtual_Machine_Management_Guide/appe-Reference_Settings_in_Administration_Portal_and_User_Portal_Windows.html#Virtual_Machine_Resource_Allocation_settings_explained
and I can wrap my head around it. Do I need to given explicit mapping for all
the 22 vCPU ? And dig in lscpu -e or numactl -H to find how each pCPU is
identified ?
